ROWLAND T. WALES, OF SEWAREN, NEW JERSEY.

MOLD FOB. oononn'rn consrnuc'rron.

' siding at Sewaren, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvements in Molds for Concrete Construction, of which the following is a specification.

This invention provides certain improvements in molds for use in building structures of concrete or similar material, or for facing or covering structures with such material. The particular construction of molds to which these improvements apply, consist of the following: There are plates against which the concrete is molded and they consist of boards or panels. They are held in position by a framework or series of supports or studs. The studs may be secured and held in position by any usual or suitable method for securing and holdingsuch members. Plates are held in position by means of locks which engage the studs. Plates are adjustable and movable relatively to the studs and adjustable into and out of position without affecting the studs. Plates are likewise adjustable and movable without affecting adjoining plates, except in special. cases. Each lock is both adjustable and movable relatively to both plates and studs and without moving studs, other looks or other plates than the plates immediately held by it. Such a construction permits using the same platesand locks repeatedlyin different parts of the same framework of studs before a job is completed. It also permits taking down the studs, after stripped of plates, and using the same supports again in another part of the job. While two studs are in any one position, a plate can be used between them repeatedly at subsequently higher levels, each removal of the plate be ing made after the concrete behind it has become only sufficiently hard to stand up in the small area which the plate has covered. The construction of'molds described in the foregoing has the following advantages:

1. Uses less mold material on a single job. 2. Uses the same mold material repeatedly and without destruction on successive jobs. 8. Is erected and dismantled quicker and with less labor.

4. Permits easy placing and supporting of any iron reinforcemnt within the mold space before the plates are locked in posi- Specification of Letters Patent.

tion. With no plates to obstruct the workmen, the individual parts of the reinforcement can be handled separately and fastened directly and accurately into their final p0- sitions and without previous assembling.

5. Possesses all advantages of panel molds without sacrificing the strength and accuracy possible by using studs as in other molds. i

This invention provides certain new and useful improvements pertaining to the construction described in the foregoing, and has the objects accomplished by these improvements are given in the following:

1. Improved means for holding looks from moving laterally.

2. Improved form of stud adapted for engagement by the improved locks shown herein and in other applications filed by me.

The'improvements give maximum strength of stud with minimum weight and cost of manufacture. a

3. An improved corner stud.

4. An improved maximum strength and minimum weight and thickness of sheet metal.

I 5. An improved metal plate adapted to. form a surface on concrete which will hold plaster.

6. An improved means by which a given number of locks will support a variable number of plates under ceilings of different spans between walls.

Various sheet metal shapes are applicable for manufacturing.the studs according to the stock of shapes available or economical and according to the character of work for plate of sheet metal with which the mold will be used. Likewise, different .parts of the locks and of other parts of the invention may be varied in construc tion orin combination, according either to requirements or to economy in manufacture. A number of examples are illustrated herewith, all of which embody essential features of this invention.

Figure l is a horizontal section showing a general view including a corner of a wall. Fig.- 2 is a partial vertical section. It shows a stud in side elevationshowing a lateral side of the stud.

Thesmarks in; the following indicate details of studs and attached parts.

A are Z bars of sheet metal extending longitudinally of the stud and between the space engaged by theglocks and the mold space. There are two, each one being disposed in a lateral side; ofthe stud, as shown. Between the two there is 'a longitudinally extending space adapted to admit tie rods f at any level and as shown in'Figs. 1 and 2.

A is a wood member adjacent the mold space and adapted to form a surface on concrete which. will hold plaster. adapted for nailing to it the members I? and t shown in Fig. 2.'

B {are ehannel shapes of sheet metal extending longitudinally of the stud and constituting its main strength; There are two in a stud, asishown, and adapted to admit between them a tie rod 7 shown in Figs. 1 and 2. I

G'and C are bolts which hold parts of a stud together as shown.

Diare spacers or small metal members which hold-members A separated from members B." They are perforated to admit bolts C which hold them as shown. The space which separates the parts A from B extends longitudinally of the stud and is adapted for engagement'by locks at any point not obstructed by the spacers D.

F'are flanges on -A to prevent plates K from entering the mold space and prevent cementfrom entering between the stud and the plates.

Hare flanges on Z bars A and extend inwardly of the stud." Conjointly with flanges J, the bolts C and the spacers D,

they constitute a means within and close to the lateral sides of the stud for holding its members together without obstructing the movement of plates at the .lateral sides of the stud. The bolts C are disposed as near as possibleto the lateral sides of the stud to prevent the lateral sides .of the stud from being bent apart at the opening between A and I J are flangeson B for thepurposeexplained under S are short bars or metal members forstiffening and bracing the lateral sides at the outward partof the stud. They are bolted to the flanges T by the vbolts C They are distributed at intervals longitudinally of a. stud as indicated in Fig. 2 by C Tare' flanges on Bto give additional strength ,and rigidity. They provide a means for connecting the opposite sides by It is also means of S and C within the lateral sides of the stud where neither S nor T will obstruct the movement of plates.

0 inFig. 2 is. a channeleshaped stringer shown in vertical cross section. It is for holding studs at proper distances apart on the same side of a wall just as stringers like it are used in other molds or concrete forms. Similar stringers c are shown in plan in Fig. 1.

c are stringers of wood just explained under a.

f in Figs. 1 and 2 are tie rods such as are used in other forms to hold studs in position. They extend transversely of the mold and generally pass each through two studs, one on each side of the wall. are often substituted by wire.

2? at the right of Fig. 2 are spacing blocks. or sticks nailed to the wood faces on A of the studs. These blocks 26 keep the studs separated at the proper distance from structural steel, or at the proper distance from studs on the opposite side of a wall or from any support or object, as required. They are shown herein to illustrate another advantage of the wood member A on the stud.

t at the right of F ig, 2 are horizontal strips nailed to the wood face of the stud to leav ornamental depressions in the concrete resembling masonry lines, and are shown herein to illustrate another advantage of the wood member A on the studs.

t at the right of Fig. 2 are verticalstrips extending between t t? and for the same purpose given above for t.

The marks in the following indicate details of. locks which engage thestuds and hold the plates adjacent the mold space.

P is the part. of a lock which carries a movable.part Q audtransmits theload to. the studz,

Q is a movable partshown in the formof a screw which is moved relatively to P inwardlyand outwardly of the mold and will, prevent outward movement of plates when Q is in position.

W is a bent end of Q which serves as a handle for turning Q.

P is a lug on P to prevent it from moving laterally of the stud.

2 is an outward extending arm on P to carry other parts ofthe locks, as shown-. Conjointly with parts which bear on the stud it prevents the lock from moving out of position. a

They

P is an arm on P which bears against a lateral side of thestud and coujointly with body portion of the lock enerally comprises one or more of the parts P P and P.

P in Fig. 3 is a spring attached to the lock and which enters the stud with P as shown. It prevents the lock from slipping i out of position when not under pressure outward of the mold from K. A slot in P" surrounds Q and permits free movement.

P in Figs. 1 and 3 is a thumb screw or clamping screw which turns within P near P and has its end adapted to bear on a lateral side of a support as it is shown bearing against B. It draws the lug P laterally and securely into position. It is adapted to prevent the lock falling from position when there is no load bearing on the look. When P is used for said purpose the spring P is not necessary and may be eliminated. P is also adapted to prevent Q from bearing laterally and directly against a support and thus disposes Q sufiiciently beyond the end of K to hold K securely. For this latter purpose the thumb screw P could be replaced by a bolt with lock nuts which secure it rigidly to P The marks in the following indicate details which pertain to plates.

K are boards which are fastened together in standard panels.

L '(see at the right of Fig. 2 where a plate is partly cut away; also see Fig. 3) is a strip facing a panel at its edge and c011- necting the boards of the panel together. It is adapted. to bear against the flanges F on the studs.

M (see at the right of Fig. 2 where a plate is partly cut away; see also Fig. 3) is an angle reinforcing the end and the edge of one face of a plate in a similar manner as L. M may or may not connect boards together in one panel, but may extend across the ends of unattached 'boards and hold them in position.

M in Figs. 5 and 6 is an angle similar to r M described above. It reinforces the end of a metal plate or panel, connects its parts and provides a bearing surface for looks. One wing of it eXtends transversely of both the mold face and the channels ('0) and forms the end face of the plate. Its other wing covers part of the open side of said channels and thus forms a face adapted to bear against said locks.

M in Figs. 5 and 6 are short angles riveted in position and connecting M with other parts of the plate as shown.

M in Fig. 5 isa metal strap reinforcing the side of a metal plate which is not reinforced by M l i o in Figs. 5 and 6 are channel shapes of thin sheet metal which, when connected side by side, form a strong and durable plate of minimum weight and with a face which will not warp or be bent out of plane.

1 in, Figs. 5 and 6 is a lap cut and bent on plates K or K in (position.

the end of a flange one. channel and is bolted to M as shown.

0 in Fig. 6 is a recess at the end of the face of the channels 1) and is for engaging flanges or members similar to F in Fig. 3.

o in Figs. 5 and 6 is a lap cut in theiend of the web of the channel 41 and bent so that it may 'bebolted to M as shown.

Plates formed of channels as illustrated in Figs. 5 and 6 are also advantageous for molding some ceilings or downward facing surfaces.

The marks in the following indicate details incorner studs, corner locks and corner plates, and are shown in Figs. 1 and 4.

M is a bearing plate connecting and reinforcing the edges of the boards or plates K whioh meet at an. outside corner of a wall. The screws Q of the corner locks bear on M and thus hold K in position. M is shown as loosely nailed to K and may be easily removed from K when not in the mold. y

M is an iron angle disposed in the inside corner formed by the boards or plates K which are connected at the inside corner of a wall. It may or may not be fastened to K The screws Q of the corner locks bear on M, as shown, and thus hold K against pressure from the mold space.

R is a corner stud supported in a crotch formed by the stringers 6 outside the outside corner of the wall. It is made of sheet metal, is hollow, and has an open side facing toward the corner of the wall. It has wings G, diverging from its open side and bearin against the stringers 6 as shown.

.1 is a corner stud similar to R and is shown supported by stringers 6 inside the inside corner of the wall. It has wings G similar to G on R.

K .is explained under M. K is explained under M". g is a spring on a lock. When a lock is placed in position, 9 and part of Q, as
